Re-viewing the CMI Framework (Re-view: Take another look, see anew) Cathy Seeley, UCTM Conference, Nov. 4, 2011 Use the implementation of the Common Core State Standards in Mathematics as leverage for improving instructional practice. CCSS-M motivates the need for new instructional practices Mathematical Practices Learning Progressions (informed both by research on children's cognitive development and by the logical structure of mathematics) De-fragmenting the Math (“Graph proportional relationships, interpreting the unit rate as the slope of the graph.”) Instructionally-demanding Verbs (“Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function.”) Naïve Perspectives on Mathematics Instruction Reform (“Math Wars”) Discovery learning “Hands-on activities” “Tons of discussion, group work, student sharing of strategies” Need for an instructional framework in mathematics education Chazan and Ball (1999) expressed frustration with “current math education discourse about the teacher’s role in discussion-intensive teaching.” They argue that educators are often left “with no framework for the kinds of specific, constructive pedagogical moves that teachers might make.” Stein et al. (2008) refer to a first generation of instructional reform from which “many teachers got the impression that in order for discussions to be focused on student thinking, they must avoid providing any substantive guidance at all,” and they refer to a second generation of instructional reform “that re-asserts the critical role of the teacher in guiding mathematical discussions.” Intent of the CMI (Comprehensive Mathematics Instruction) Framework Cognitive Demand (the nature of worthwhile tasks) Five Practices (orchestrating mathematical discourse) Sociomathematical Norms (teacher’s role in creating learning environments that press for understanding) Landscape of Learning (conceptual, procedural, representational domains of mathematics) NCTM Process Standards / Mathematical Practices (engaging in authentic mathematical practice) Learning Trajectories and Progressions (curriculum design) Depth of Knowledge (DOK) Assessment Mathematical Knowledge for Teaching (MKT) Reflective Practitioner (INTASC Standards) Three components of the CMI Framework The Teaching Cycle (addresses pedagogy, the learning environment, orchestrating discourse, and formative assessment) The Learning Cycle (addresses the cognitive demand of tasks, flow of the unit, content standards and learning trajectories, process standards and mathematical practices, formative and summative assessment) The Continuum of Mathematical Understanding (addresses conceptual, procedural, and representational thinking; depth of knowledge; and assessment) The Teaching Cycle PEDAGOGICAL PRACTICES SUPPORTED BY THE TEACHING CYCLE: Using Student Thinking Anticipate Student Thinking Connect Student Thinking Select and Sequence Student Thinking Monitor Student Thinking PEDAGOGICAL PRACTICES SUPPORTED BY THE TEACHING CYCLE: Learning Environment Sociomathematical norms: criteria for attending to and judging the work of peers Determine groupings: individual, pairs, small group Tools to support exploration and discourse PEDAGOGICAL PRACTICES SUPPORTED BY THE TEACHING CYCLE: Formative Assessment What’s next? What are students taking away from the discussion? Have we activated appropriate background knowledge? Provided enough information while maintaining the problematic nature of the task? When are students ready to move to the Discuss stage? PEDAGOGICAL PRACTICES SUPPORTED BY THE TEACHING CYCLE: Mathematical Discourse Teacher’s role: Orchestrate the structure and flow of the discussion. Students role: Explain and justify one’s own thinking; Clarify, describe, compare, question the thinking of others. Teacher’s role: Launch and clarify the task. Teachers role: Ask questions to engage, prompt, guide, clarify, deepen student thinking. The Learning Cycle The purpose of a Develop Understanding lesson is to surface student thinking. The purpose of a Solidify Understanding lesson is to examine and extend student thinking. The purpose of a Practice Understanding lesson is to acquire fluency and refine student thinking – enabling students to transfer understanding to new “communities of practice”. CURRICULUM DESIGN PRINCIPLES SUPPORTED BY THE LEARNING CYCLE What constitutes a Worthwhile Mathematical Task? Contextualized or abstract/symbolic? Amount of scaffolding provided? Constraints? Level of cognitive demand? CURRICULUM DESIGN PRINCIPLES SUPPORTED BY THE LEARNING CYCLE Thinking Through a Unit Ideas: What do we want students to know? Strategies: What do we want students to be able to do? Representations: How do we want students to make their thinking visible? How do ideas, strategies and representations differ from the beginning to the end of a unit of instruction? The Continuum of Mathematical Understanding KEY ASPECTS OF THE CONTINUUM Three distinct domains of understanding: conceptual, procedural, and representational Words were chosen to indicate movement across the continuum. For example, ideas that are examined and extended become more solid which we call concepts, and concepts that are refined and fluent become practiced which we call definitions and properties. This is a continuum, not discrete jumps Ovals represent the work within teaching cycles Left to right movement along the continuum represents movement from specific to general, from concrete to abstract Connections between domains creates movement along the continuum; therefore, one can’t discuss procedures with understanding without referring to the conceptual and representational domains. Design Criteria for Learning Cycle Tasks It will be sufficient for participants to use the criteria for cognitive demand to select and adapt tasks to fit the learning cycle. “Doing Mathematics” tasks generally fit the role of surfacing understanding and make good Develop Understanding tasks. “Procedures with Connections” tasks generally allow students to examine an extend understanding and make good Solidify Understanding tasks. “Procedures without Connections” tasks always focus on acquiring fluency and may be used as Practice Understanding tasks, along with games, etc. (Generally, low cognitive demand tasks can fit practice understanding goals, but practice understanding tasks don’t have to be low level tasks; strategic games can provide practice and yet be at a high level of cognitive demand. Tasks that refine understanding generally involve modeling and other high level, cognitively demanding work.)
